An EMC customer is evaluating a single-engine EMC Disk Library (EDL) system. They placed the EDL on their test infrastructure and performed 15 simultaneous backup jobs. The customer is concerned that the overall performance numbers are substantially lower than the published numbers.Each job is sent to a separate virtual tape at an average rate of 18 MB/s. The EDL is connected to the SAN through two FC ports at 4 GB/s. There are a total of 15LUNs for virtual tape storage. The infrastructure has been certified to sustain performance in excess of the EDL's capability.What would you recommend to improve the overall performance?
A Symantec NetBackup customer is planning to add a second data center. They would like to leverage deduplication technology to improve backup operations and disaster recovery with a minimum amount of change to their existing backup environment. The customer's primary design goals are:1. Improve backup performance2. Electronic vaulting for disaster recovery3. Maintain NetBackup as their primary tool for backup control and visibilityWhat should be included with a high-end Data Domain appliance?
A customer has two files that have been locked and backed up to the Data Domain appliance with the following parameters:File1 = atime = 20 yearsFile2 = atime = 5 yearsThe Data Domain global retention periods are configured as follows:Min = 2 yearsMax = 10 yearsThe administrator changes the Data Domain maximum retention period to 4 years. After how many years can File2 be deleted?
A customer performs weekly full backups and daily incremental backups. A typical full backup is 5 TB. There is usually a 20% daily change rate in data. A full backup completes in 10 hours while an incremental backup completes in 4 hours.Based on best practices, what is the minimum Data Domain throughput required?
The EMC account team has been asked to design a NetWorker backup solution. The customer's environment consists of a Microsoft Exchange Server 2007Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.The customer wants to leverage the Microsoft VSS framework to back up their Exchange server from the Exchange Server 2007 CCR passive node. What needs to be considered when designing this backup solution?
A customer is implementing s Data Domain system with two expansion shelves. They require that access to the data can be reached even when a single path fails. The customer does not want the HBA card to be the single point of failure.A.B.C.D.
